Abstract
A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.
